[−][src]Struct abi_stable::std_types::slice_mut::RSliceMut
Ffi-safe equivalent of &'a mut [T]
Methods
impl<'a, T> RSliceMut<'a, T>
[src]
pub const fn len(&self) -> usize
[src]
The length (in elements) of this slice.
pub unsafe fn from_raw_parts_mut(ptr_: *mut T, len: usize) -> Self
[src]
Constructs an RSliceMut<'a,T>
from a pointer to the first element,
and a length.
Safety
Callers must ensure that:
-
ptr_ points to valid memory,
-
ptr_ .. ptr+len
range is àccessible memory. -
ptr_ is aligned to
T
. -
the data ptr_ points to must be valid for the lifetime of this
RSlice<'a,T>
impl<'a, T> RSliceMut<'a, T>
[src]
pub fn from_mut(ref_: &'a mut T) -> Self
[src]
Converts a mutable reference to T
to a single element RSliceMut<'a,T>
.
Note:this function does not copy anything.
pub fn slice<I>(&self, i: I) -> RSlice<T> where
[T]: Index<I, Output = [T]>,
[src]
[T]: Index<I, Output = [T]>,
Creates an RSlice<'a,T>
with access to the range
range of elements.
This is an inherent method instead of an implementation of the ::std::ops::Index trait because it does not return a reference.
pub fn slice_mut<'b, I>(&'b mut self, i: I) -> RSliceMut<'b, T> where
[T]: IndexMut<I, Output = [T]>,
[src]
[T]: IndexMut<I, Output = [T]>,
Creates an RSliceMut<'a,T>
with access to the range
range of elements.
This is an inherent method instead of an implementation of the ::std::ops::IndexMut trait because it does not return a reference.
pub fn to_rvec(&self) -> RVec<T> where
T: Clone,
[src]
T: Clone,
Creates a new RVec<T>
and clones all the elements of this slice into it.
pub fn as_slice(&self) -> &[T]
[src]
Creates an &'_ [T]
with access to all the elements of this slice.
pub fn into_slice(self) -> &'a [T]
[src]
Creates an &'a [T]
with access to all the elements of this slice.
This is different to as_slice
in that the returned lifetime of
this function is larger.
pub fn as_rslice(&self) -> RSlice<T>
[src]
Creates an RSlice<'_, T>
with access to all the elements of this slice.
pub fn into_rslice(self) -> RSlice<'a, T>
[src]
Creates an RSlice<'a, T>
with access to all the elements of this slice.
This is different to as_rslice
in that the returned lifetime of
this function is larger.
pub fn as_mut_slice(&mut self) -> &mut [T]
[src]
Creates a &'_ mut [T]
with access to all the elements of this slice.
pub fn into_slice_mut(self) -> &'a mut [T]
[src]
Creates a &'a mut [T]
with access to all the elements of this slice.
This is different to as_mut_slice
in that the returned lifetime of
this function is larger.
